User space data storage management

A computer system, comprising:

• one or more processors;
• and
• memory divided into a kernel space and a user space, the memory storing one or more programs, which when executed by the one or more processors cause the computer system to:
• send, by a first user space module implemented in the user space, a logical memory request to a kernel space memory management module of a kernel space module implemented in the kernel space, wherein the logical memory request includes data and metadata;
• obtain, by a second user space module implemented in the user space, the metadata of the logical memory request;
• determine, by a storage engine of the second user space module, in accordance with the obtained metadata, a location for the data in non-volatile memory of a storage device;
• generate, by the second user space module, a physical memory request including an indication of the location in the non-volatile memory for the data;
• and
• transmit, by the second user space module, to the kernel space memory management module, the physical memory request.

A non-transitory computer readable storage medium, storing one or more programs configured for execution by one or more processors of a computer system comprising a memory divided into a kernel space and a user space, the one or more programs including instructions that when executed by the one or more processors of the computer system, cause the computer system to:

• send, by a first user space module implemented in the user space, a logical memory request to a kernel space memory management module of a kernel space module, implemented in the kernel space, wherein the logical memory request includes data and metadata;
• obtain, by a second user space module, the metadata of the logical memory request;
• determine, by a storage engine of the second user space module implemented in the user space, in accordance with the obtained metadata, a location for the data in non-volatile memory of a storage device;
• generate, by the second user space module, a physical memory request including an indication of the location in the non-volatile memory for the data;
• and
• transmit, by the second user space module, to the kernel space memory management module, the physical memory request.
